These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Cliché Storm: The film is just the typical "underdog overcomes the odds and wins in the end" story, except the characters are planes and cars.
Critical Dissonance: Critics hated the film, regarding it as a bland retread of Cars created only to sell more toys. This didn't stop the film from making back its budget.
Double Standard: There have been complaints on feminist sites such as Jezebel about how while there are two female planes racing, they are considered as love interests instead of actual competition. They seem to miss the point that Ishani is a Pan-Asian Champion and Rochelle got into racing as, when she was a postal plane, she'd fly as fast as possible to help those who needed spare parts.
Then again, both were minor characters who lacked any arc and were treated largely as love interests.
Fridge Horror: Skipper's squadron being shot down on-screen, since the planes themselves are alive. Rough stuff for a kid's movie
WWII exists in this world. That means there was a car/Plane Hitler, and thus a carlocaust...
Cue the mental image of Volkswagen beetles doing the car equivalent of goosestepping.
And of course, for there to be a WWII, there must first be a WWI. Which makes one wonder how trench warfare works if everyone (on land) is on wheels.
Mis-blamed: Much of the Hatedom for this movie is aimed at Pixar despite the movie being written and designed by DisneyToon Studios and animated by Prana Studios in India (due to outsourcing).
Moral Event Horizon: Ripslinger sending Ned and Zed to sabotage Dusty during the China-Mexico stretch.
